APPARATUS FOR BURNING NATURAL GAS.

SPECIFICATION forming part of Letters Patent No. 457,245, dated August4, 1891.

Application filed January 29, 1891. Serial No. 379,536. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES D. BET'rs, a citizen of theUnited States,residing at Warren, in the county of arren and State of Pennsylvania,have invented new andvuseful Improvements in Apparatus for BurningNatural Gas, of which the following is a specification. I

This invention has for its object to provide a novel apparatus forburning natural gas in heating stoves, ranges, furnaces, and othersimilar structures, and to provide novel means whereby the burner-headcan be rotated or vention for burning natural gas.

turned in a horizontal plane parallel with the horizontal plane of thegas-conduit upon which the burner-head is journaled for the purpose 0tcontrolling the flow of natural gas from the conduit into theburner-head.

To accomplish these objects my invention involves the features ofconstruction, the combination or arrangements of parts, and theprinciples of operation hereinafter described and claimed, referencebeing made to the accompanying drawings, in which Figure 1 is aperspective view of an apparatus constructed in accordance with my iniFig. 2 is a longitudinal sectional view taken on a vertical planecentrally through the apparatus. Fig. 3 is a transverse sectional viewtaken on the line 00 00, Fig. 2; and Fig. 4B is a detail 7 perspectiveview looking at the under side of one of the burner-heads 'to moreclearly exhibit its stud-journal.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to thedrawings, where The numeral 1 indicates a hollow casing, which ispreferably rectilinear in the direction of its length and square orrectangular in cross-section to form a flat bottom wall 2 and parallelupright side walls The horizontal top wall 4 of the casing is a separatepiece and is secured in place by vertical screwbolts 5, or similarattaching devices, of such construction that the top plate can beconveniently removed or replaced if occasion demands. The casing,constructed as described, constitutes a gas-conduit, which at one end isprovided with a screw-threaded neck 6, by which to couple it to a pipewhich supplies the natural gas to be burned. The detachable top wall ofthe conduit is provided near each end with a series of gas-orifices 7,pref- 5 5 erably in the form of segmental slots, and between each set oforifices the 'top wall is formed integral with a socket S to receive thecylindrical stud-journal 9, formed centrally wit-h the base-plate 10 ofa burner-head 12. These base-plates 10 are each provided with segmentalorifices 13, adapted to register with. the orifices 7 in the top wall ofthe gas-conduit in such manner that by axially rotating the burner-headin a horizontal plane which is parallel with the horizontal plane of thegas-conduit the orifices in the burner-head can be placed into or out ofcoincidence with theorifices 7 in the top wall of the gas-conduit,whereby it is possible to vary the quan- 7o tity of gas flowing into-theburner-head or to entirely out off the burner-head from communicationwith the gas-conduit.

.The top wall of the gas-conduit is provided near each end with aprojecting annular 7 5 flange or rib 14, to form seats or bearings forthe base-plates of the burner-heads, the construction being such thatthe latter project at right angles, or approximately so, to thegasconduit. 8

The burner-heads are each composed of the base-plate described and ahollow or cupshaped plate or shell 15, provided in its edge, which restson the base-plate, with gas-delivery orifices 16, and in its bodyportion with divergent gas-delivery orifices 17. The cupshaped plate orshell is secured into fixed position by a vertical screw or bolt 18,passing through the stud-journal 9 of the baseplate 10, for the purposeof rigidly connect- 9o ing these parts so that they rotate or turn inunison. r

The burner-heads are each provided with a pair of separate lugs or ears19 to receive between them a suitable implement, such as 5 a poker, forthe purpose of rotating or turning the burner-head to place itsgas-orifice 13 into or out of coincidence with the gasorifices 7 in thegas-conduit.

I have exhibited thegas-conduit as provided with a pair of rotaryburner-heads; but obvi ously a greater or less number can be employedwithout departing from the spirit of my invention.

By my improved construction I provide a x 0 novel, simple, and efficientapparatus for burning natural gas to utilize the latter in heatingstoves, ranges, and similar structures, while the most simple means arepresent which render it convenient to vary the fiow of gas from theconduit to the burner-head, or to e11- tirely out off the flow of gasinto such burnerheads, By this means I am enabled to arrange a series ofburner-heads on a single gasconduit for natural gas, whereby any one orall of such burner-heads can be promptly cut off from communication withthe gas-conduit without the necessity of employing an ordinary cock orvalve for controlling the flow of gas to each burner, as in thoseburners where 2 5 independent gas-conduits connect with separatesections of a gas-burner, and each conduit is provided with a cock orvalve of ordinary construction to control the flow of gas therethroughto the burner.

I am aware that a burner-tip for illuminating-gas has been made to"rotate for cutting off the passage of the gas through the burner to thetip; but the prior construction is not practicable for natural gas, and,further, the 3 5 arrangement of parts is substantially and materiallydifferent from that described and shownby me.

An important feature involved in my construction and mode of operationresides in the s fact, as before stated, that I can employ a pluralityof burner-heads with a single gasconduit and throw any one or all ofsuch burner-heads into or out of action by simply rotating it in ahorizontal plane which is parv 5 allel to the horizontal plane of thegas-conduit. This arrangement and principle of operation provides apracticable structure to utilize natural gas forheatingpurposes, whilethe apparatus is simple, economical, and not liable to becomeinoperative.

The main body portion of the gas-conduit, comprising the bottom wall 2and the side Walls 3, is preferably a single casting, and likewise thetop wall 4 is preferably a single 5 5 casting, while the parts of theburner can also be cast, thereby enabling the apparatus to beeconomically manufactured. The top wall of the casing or conduit isprovided with a series of jet-orifices 20, arranged near each one of therotary burners, so that the gas will at all times burn at thesejet-orifices 20 for the purpose of igniting the gas issuing from aburner should it be turned off and subsequently turned on. In practice,if one of the burners be turned to close the supply of gas thereto andsubsequently be turned to permit the flow of gas from the burner, theescaping gas would likely cause an explosion if the gas issuing from theburner were not promptly relighted. The provision of the relightingjet-orifices fulfills the conditions required to instantly ignite thegas issuing from a burner if the latter should be turned off andsubsequently turned on. I may also provide the side walls of the conduitor casing with similar reli ghiin g j et-orifices 21, but these orificesare preferably placed in the top wall of a casing or conduit, althoughboth constructions may be employed.

Instead of connecting the gas-supply pip with a screw-neck 6 at one endof the conduit or casing, I may provide the bottom wall of the conduitor casing with a screw-threaded socket 22 for connecting with agas-supply 1 1 e. P l VIy improved burneror apparatus for utilizingnatural gas in heating stoves, ranges, and furnaces is desirable owingto facility afforded for conveniently cleaning it. This is renderedpossible by the detachable top wall and by the fact that theburner-heads can be readily removed by simply lifting theirstud-journals from the socket-bearings, while the burner-head itself isin sections capable of convenient separation.

Having thus described my invention, what I claim is 1. An apparatus forburning natural gas, consisting of a gas-conduit having gas-orifices,and a rotary burner-head projecting from the gas-conduit at right anglesto the length thereof and having its base-plate provided withgas-orifices to register with those in the gas-conduit, said burner-headrotating in a plane parallel with a horizontal plane through the lengthof the gas conduit, substantially as described.

2. An apparatus for burning natural gas, consisting of a gas-conduithaving a wall provided with asocket-bearing and gas-orifices, and arotating burner-head having a base portion provided with gas-orificesand a projecting stud-journal arranged in the socket-bearing of saidwall, whereby the gas-orifices in the base of the burner-head are placedinto and out of coincidence with the gas-orifices in the wall of theconduit by the rotary movement of the burner-head, substantially asdescribed.

3. An apparatus for burning natural gas, consisting of a conduit havinga wall provided with gas-orifices and a rotating burnerhead having astud-journal connection with the said wall and provided withgas-orifices, and a pair of projecting lugs or cars for the receptionbetween them of an implement for axially turning the burner-head, andthereby placing its gas-orifices into and out of coincidence with thosein the wall of the conduit, substantially as described.

4. An apparatus for burning natural gas, consisting of a gas-conduitprovided with rotating burner-heads and. gas-orifices which are openedand closed by rotating the burnerhead, and relighting jet-orificesextending through a wall of the casing 0r conduit'for the purpose ofrelighting the gas issuing from a. burner if the latter be turned offand subsequently turned on, substantially as described.

In testimony whereof l have hereunto set my hand and affixed my seal inpresence of to two subscribing witnesses.
